In the introduction to the novel, Niven says that he never planned to write more than one Ringworld novel, but that he did so, in a large part, due to fan support. Firstly, the popularity of Ringworld resulted in a demand for a sequel. Secondly, many fans had identified numerous engineering problems in the Ringworld as described in the novel. The first major problem was that the Ringworld, being a rigid structure, was not actually in orbit around the star it encircled and would eventually drift, resulting in the entire structure colliding with its sun and disintegrating. In the novel's introduction, Niven says that MIT students attending the 1971 World Science Fiction Convention chanted, "The Ringworld is unstable! The Ringworld is unstable!" Niven says that one reason he wrote The Ringworld Engineers was to address these engineering problems.
Plot summary
The Hindmost, recently deposed leader of the Puppeteers, abducts the human Louis Wu (who has become a wirehead) and KzinChmeee (previously known as "Speaker-to-Animals"). Both had been part of the original Ringworld expedition. The Hindmost hopes to acquire Ringworld technology, specifically matter transmutation, to help him regain his position.
Once they reach the Ringworld, Louis and Chmeee are sent out to explore, while the Hindmost remains safely behind on their starship. Louis and Chmeee secretly plot to try to overthrow the Hindmost so they can go home. In their travels, they meet a number of the hominidspecies that have evolved on the Ringworld. They also learn more about the full-scale "maps" of various known space worlds, including Earth, Mars and Kzin.
They discover that the Ringworld has become unstable and will collide with its star soon. The Ringworld's builders, revealed to be Pak Protectors, have long since died out, and the attitude jets they installed all around the rim to maintain the Ringworld's position were dismounted to use as starship engines. Chmeee goes to the Kzin map for his own goals, while Louis tries to find some way to save the trillions of inhabitants.
It is on the Map of Mars that the reunited party (and two natives) finds the Ringworld control room Louis is seeking, located in a vast maze of rooms in the hollow space under the map. To create the rarefied atmosphere on Mars, the Map of Mars was built 20 miles (32km) above the main surface, creating a 1,120,000,000-cubic-mile (4.7×109km3) cavity. The control room contains living space and, among other things, the meteor defense system. The defense system uses the superconductor grid embedded in the Ringworld's scrith floor to manipulate the magnetic field of the Ringworld's sun to trigger stellar flares that power a titanic gas laser. (The first expedition to the Ringworld crashed after being hit by this laser.)
They encounter Teela Brown, a human member of the first expedition who had chosen to remain on Ringworld. She and her lover Seeker had, in the course of their travels, stumbled upon "Tree-of-Life" plants. The smell of the plant drove them to eat its roots; Teela was turned into a Pak Protector, with superhuman intelligence and strength, but Seeker died, being too old to undergo the transformation. As a Pak Protector, Teela has little control of her actions; her protective instincts force her to try to save all of the Ringworld inhabitants. This causes a dilemma. She knows of a way to save the Ringworld, but it would entail killing 5% of the people. This she cannot do. She manages to lure Louis and the others to where they can save the other 95%. Her instincts make her fight them, but she does so half-heartedly so that they can kill her.
Afterward, Louis figures out what to do. Teela had restored starship engines to their original purpose as attitude jets, but only had enough for 5% of the ring. Louis explains that the meteor defense system can generate a massive stellar flare (normally used to power the laser weapon) to provide twenty times more fuel to the attitude jets to move the Ringworld back into position. However, the radiation from the flare will be fatal to everything and everyone living on that section of the Ringworld. The actual task is carried out by the Hindmost, who is far superior at operating the control systems (and can safely pass through a Tree-of-Life plantation en route to the control center, as Louis cannot).
Having earlier destroyed the hyperdrive to force the Hindmost to cooperate, Louis is stranded. He and the rest of his party look for some place to settle down, while the Hindmost remains aboard the disabled (but very safe) starship to think things over.

The Chicago Sun-Times wrote: "For new readers, there’s fascinating adventure in plenitude. For old fans of Niven’s Known Space series, or of the original volume, there are all the fine, characteristic touches that delight us Niven fans, and which support his reputation for uncommon wittiness and fast narrative pace."[3]
Thomas M. Wagner of SFreviews.net reviewed the book in 2001 and gave it a 4 out of 5 rating. Wagner rated it higher than the first book. He found some of the storytelling outdated but overall praised Niven for "a consummate professional's skill at balancing imagination and science harmoniously."[4]
Laurence van Cott Niven is an American science fiction writer. His 1970 novel Ringworld won the Hugo, Locus, Ditmar, and Nebula awards.

Known Space is the fictional setting of about a dozen science fiction novels and several collections of short stories by American writer Larry Niven. It has also become a shared universe in the spin-off Man-Kzin Wars anthologies. The Internet Speculative Fiction Database (ISFDB) catalogs all works set in the fictional universe that includes Known Space under the series name Tales of Known Space, which was the title of a 1975 collection of Niven's short stories. The first-published work in the series, which was Niven's first published piece, was "The Coldest Place", in the December 1964 issue of If magazine, edited by Frederik Pohl. This was the first-published work in the 1975 collection.
Ringworld is a 1970 science fiction novel by Larry Niven, set in his Known Space universe and considered a classic of science fiction literature. Ringworld tells the story of Louis Wu and his companions on a mission to the Ringworld, a rotating wheel artificial world, an alien construct in space 186 million miles in diameter. Niven later added three sequel novels and then cowrote, with Edward M. Lerner, four prequels and a final sequel; the five latter novels constitute the Fleet of Worlds series. All the novels in the Ringworld series tie into numerous other books set in Known Space. Ringworld won the Nebula Award in 1970, as well as both the Hugo Award and Locus Award in 1971.
The Ringworld science fiction role-playing game was published by Chaosium in 1984, using the Basic Role-Playing system for its rules and Larry Niven's Ringworld novels as a setting.

Pierson's Puppeteers, often known just as Puppeteers, are a fictional alien race from American author Larry Niven's Known Space books. The race first appeared in Niven’s novella Neutron Star.
Pak Breeders and Pak Protectors are two developmental stages of fictional life in Larry Niven's Known Space universe. The Pak first appeared in "The Adults", which appeared in Galaxy in 1967; this story was expanded into the novel Protector by Larry Niven (1973). The Pak also appear in several of Niven's later novels, notably those set in the Ringworld.

"Neutron Star" is an English language science fiction short story by American writer Larry Niven. It was originally published in the October 1966 issue of Worlds of If. It was later reprinted in the collection of the same name and Crashlander. The story is set in Niven's fictional Known Space universe. It is notable for including a neutron star before their existence was widely known.
Protector is a 1973 science fiction novel by American writer Larry Niven, set in his Known Space universe. It was nominated for the Hugo in 1974, and placed fourth in the annual Locus poll for that year.
The Ringworld Throne is a science fiction novel by American writer Larry Niven, first published in 1996. It is the direct sequel to his previous work The Ringworld Engineers (1980). He wrote it as a replacement after being unable to finish his contracted novel The Ghost Ships, the sequel to The Integral Trees and The Smoke Ring.
The Man-Kzin Wars is a both the name of series of military science fiction anthologies as well as the name of the first book in the series. The short stories detail the eponymous conflicts between mankind and the Kzinti, set in Larry Niven's Known Space universe. However, Niven himself has written only a small number of the stories; most were written by other science fiction writers, as Niven opened this part of the Known Space to collaboration in the form of a shared universe. The cover art for the books in the series is created by Stephen Hickman.

Deryni Rising is a historical fantasy novel by American-born author Katherine Kurtz. It was first published by Ballantine Books as the nineteenth volume of the Ballantine Adult Fantasy series in August 1970, and was reprinted at least ten times over the next three decades. In 2004, the author released a revised and updated edition of the novel that was published by Ace Books. Deryni Rising was the first of Kurtz' Deryni novels to be published, though some of her later works served as prequels, detailing events that occurred before the time period of Deryni Rising. As a result, the storyline of the Childe Morgan Trilogy immediately precedes Deryni Rising, despite the fact that it was published over thirty years after the first novel.
Camber of Culdi is fantasy novel by American-born author Katherine Kurtz. It was first published by Ballantine Books on June 12, 1976. It was the fourth novel in Kurtz' Deryni novels to be published, and the first book in her second Deryni trilogy, The Legends of Camber of Culdi. The Legends trilogy serves as prequels to The Chronicles of the Deryni series that Kurtz wrote from 1970 to 1973, and it details the events that occurred two centuries before the Chronicles trilogy. Therefore, although it was the fourth Deryni novel to be published, Camber of Culdi is the earliest novel to occur within the series' internal literary chronology.
Star Gate is a science fantasy novel by American writer Andre Norton, published by Harcourt, Brace & Company in 1958. The story is science fiction with a blend of sword and sorcery, mingling technologically advanced humans from Earth with the human natives of the far-off world of Gorth and a native culture that has achieved the development level of medieval Europe.
